Application filed April 14, 1923. Serial Noi 681L009. i I

To all whom it may concern:

Be it known that I, J AMESMILES, a citizen of the United States,residing at Los Angeles, in the county of Los Angelesand 5 StateofCalifornia, have invented a new and useful Agitating Device, of whichthe following is a specification. V

This invention relates to an agitating device which is intended to beespecially use- 111 for mixing paint or any other substance held in anopen receptacle. Paint which has stood for some time in areceptacleusually becomes more or less solid or pasty at the bottom, and it is thecommon practice to mix the paint under such conditions with a stick or'a similar. implement, This gives unsatisfactory results. It has beenattempted to use a device with blades for:this

purpose, and in such use it is necessary for the lowest blade to restupon the bottom of the vessel containing'the paint; and unless thedevice is held androtated with its axis nearly vertical, the. lowestblade vwill not maintain contact with-the bottom of the vessol, and thedevice, therefore,'o crates inetficiently. The general object othisinvention is to provide an agitating device of sine ple constructionwhich will'overcomethese 'difiiculties and which is constructed in sucha way that the axis of rotation of the device need not be held exactlyvertical; that is to say, my object is. to provide a device of this kindwhich will operate effectively in spite of the fact that the axis ofrotation may be considerably inclined from the vertical line.

A further object of the invention is to provide a device. of this kindwith simple means for effecting the rotation. Further objects of theinvention will appear hereinafter.

The invention consists in the novel parts and combination of parts to bedescribed liereinafteigall of which contribute to produce an eflicientimitating device.

15 ..A preterredem odiment of the invention is described in thefollowing specification while the broad scope of the invention ispointedout in the appended claims. 1

"lhese blades are attached at theirmiddle oints, that is to"say,--at.their, center of for example. I may simply provide the upper end of theshaft 1 with a tang (5 constructed to fit into the chuck T of anordinary brace 8 such as used by carpenters to operate an anger. Thisbrace has a crank 9 with agrip ltl't'or rotating the shaft, and isprovided'at its upper end with a-swivel-head 11, the axis of rotation ofwhich is substantially in line with the axisottho shaft 1.

In the embodiment of the invention shown in Figure 2 the brat-e portion12 of the device is constructed as an integral part of it, that is tosay. the upper end of the shaft is merely bent to form a crank 1 and isprovided with a swivel-head 15.

In the embodiment of the invention shown in Figure 3, I provide a singlecrank-arm 16 which is formed by bending over the upper end ot' theshaft. and I provide a swivel grip 17 just below this rranlcarm. Theouter portion of the crank has an upward exten sion or wrist pin" 18 theupper end oi whiehcarries a swivel-head it).

The lower ends of the agitators shown in Figures 2 and 3 may becomtrueted in sub stantially the same manner as that illustrated inFigure 1. In using the agitator, it is. placed with its shaftin anupright. position so that the lowermost blade 2 rests upon the bottom 20otthe paint receptacle, the outline of which is indicated by the dottedlines 21 in-Figure 1. The-shaft is then rotated, and in rotating it, itis unnecessary to maintain it in a true vertical position, that ist'osay, t-heshaft could beheld in an inclinedpositi'on such as thatindicated by the dotted lines 22. -When held in aninclined position androtated, it will be evident that the bottom blade 2 will'rotate with theshaft as it rotates and at the same time it will rotatQ-on the axis ofits pivot 3 so as to maintain itself substantially in engagement withthe-bottom of-the receptacle.

In using the agitator when constructed as illustrated in Figure 3, ifdesired the hand which holds the grip 17 may be held stationary and thecrank 16 revolved about it. This will give the same character of movemto-thefoot of the agitator as occurs in embodiment shown in Figure-LBut, if

desired, theagitator may beoperated by sei'zihgthe hand grip 17' and theswivel head 19* and. thenmovin eachof these parts through a; small ciroe so that the real axis of'rotation of the device will become adisplhcedvert/ic-al line suchas the line 23 disposed between the shaftbody and the wrist 18 This will give the foot of the agitator a sweepingmovement on the bottom of'the receptacle and will increase the range ofmovement of the blades. At the same time, it will be evident that theblades will rotate as they move around in their circles or forbits andin case the-body of the shaft 115 not held in atrue vertical positionthe lowermost blade 24 of the device will constantly maintain itself insubstantial engagement with the bottom of the receptacle.

By reason of the fact that the device has more than one blade, and alsodue to the fact that the blades are pivoted atzt heir middle points andin ditierent transverseplanes with respect to each other, they cooperateto maintain the lower end of the shaft in a more or less centralposition in the receptacle. \Vhore a. device of this kind, but with asingle blade at. its lower end is used without any guiding means, theends of the blade tend to hold themselves against the side of thereceptacle so that as rotation takes place, the blade simply skatesaround-against the inner face ofthe wall-of the receptacle. But with myconstruction, the end of: the cross blade would engage the wall ofthereeeptaclo and prevent this.

It desired, the blades may have a slight pitch, giving them the effectof impellers to produce a slight upward movement of the paint from thebottom.

It is understood that the embodiment of the invention described hereinis only one of'the many embodiments this invention may take and I donotwishto-be= limited in the practico'of my invention-non i'rrmy claim tothe partioularembedimenb set forth;

What I claim is 1. An agitating device for-mining paints or the likeinan open metallic receptacle, comprising ashaft ltaving a-blnntl lowerend adapted to engage without penetrating the bottom of: the receptacle,and havingmeans at its upper end for rotating it on ll'S axis,andoperat'ing, when held in ones hands, to hold the shaft substantiallyupright, said shaft having a plurality-oftransverse blades attached attheirmiddle points to its lower end, said blades beingidisposedindifferent transverseplanes operating to maintain the shaftin asubstantially centml position as it is rotated in the receptacle,the-lowermost blade-being looselymounted on the'shett, and operating totilt: with respect to the shaft, and maintain itsel'f 'in enagement'withthe bottom of the paint'reeeptaclein anyupf for connection when theshaft is held' a'nd' r0-' tated in a position inclined to the plane-ofthe bottom of the receptacle, so as to mainsaid blades cooperating tomaintain the tain itself substantially in engagement with lower end ofthe shaft in a more or less centhe bottom of the receptacle during theentral position in the receptacle.
